Official abstract text for this publication.
Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed in which the hydrocarbon reactant and a supported transition metal catalyst—containing molybdenum, tungsten, or vanadium—are irradiated with a light beam at a wavelength in the UV-visible spectrum, optionally in an oxidizing atmosphere, to form a reduced transition metal catalyst, followed by hydrolyzing the reduced transition metal catalyst to form a reaction product containing the alcohol compound and/or the carbonyl compound.

We claim: 1. A supported transition metal catalyst comprising: a silica-coated alumina having a weight ratio of alumina to silica from 1:5 to 5:1; and from 0.01 to 50 wt. % of a transition metal comprising molybdenum, tungsten, vanadium, or a combination thereof, based on the weight of the supported transition metal catalyst. 2. The catalyst of claim 1 , wherein: the supported transition metal catalyst comprises from 0.2 to 10 wt. % of the transition metal, based on the weight of the supported transition metal catalyst. 3. The catalyst of claim 1 , wherein the supported transition metal catalyst comprises from 0.1 to 15 wt. % of the transition metal, based on the weight of the supported transition metal catalyst. 4. The catalyst of claim 3 , wherein the weight ratio of alumina to silica is from 1:3 to 3:1. 5. The catalyst of claim 3 , wherein the transition metal comprises molybdenum. 6. The catalyst of claim 3 , wherein the transition metal comprises tungsten. 7. The catalyst of claim 3 , wherein the transition metal comprises vanadium. 8. The catalyst of claim 3 , wherein the weight ratio of alumina to silica is from 1:1 to 3:1. 9. The catalyst of claim 8 , wherein the transition metal comprises molybdenum. 10. The catalyst of claim 8 , wherein the transition metal comprises tungsten. 11. The catalyst of claim 8 , wherein the transition metal comprises vanadium. 12.
